Tweco 1040-1887 VELOCITY2 Supra Xt Mig Gun 400A 25ft

Product Description

The TWECO 1040-1887 is a 400-amp heavy-duty MIG welding gun in the VELOCITY2 SUPRA XT VSEHD series, built for continuous high-output welding across demanding industrial environments. The gun ships with a 25-foot cable assembly and handles wire up to 1/16 inch diameter. A three-layer conductor tube construction — copper tube, silicon-resin glass insulator, and metal jacket — threads directly into the front block for improved electrical conductivity and heat management. Designed for spray transfer and pulse welding modes, it accepts straight CO2 or mixed shielding gases. Licensed welders and fabricators working in high-duty-cycle applications are the primary installers.

The SUPRA XT VSEHD is suited for heavy-duty fabrication settings where a standard-duty gun would cycle out too quickly. Typical applications include automotive manufacturing, general industrial fabrication, shipbuilding and offshore yard work, steel industry production welding, and repair and maintenance operations. The 25-foot cable length provides reach flexibility for in-position and out-of-position work on larger weldments and structural assemblies.

Key Features

• 400-amp output rating handles high-duty-cycle and spray transfer welding
• Accepts wire up to 1/16 inch diameter for a range of filler metal options
• Three-layer conductor tube (copper tube, silicon-resin glass insulator, metal jacket) threads into front block for superior electrical conductivity
• High impact-resistant one-piece straight handle with reversible trigger position — top or bottom mounting
• Metal paddle-style trigger lever with micro-switch design for reliable start/stop wire feed control
• Front and rear spring strain relief eliminates cable kinking at both ends of the handle
• Compatible with spray transfer mode, pulse welding, straight CO2, and mixed shielding gases

Compatibility

Designed as a heavy-duty OEM-style MIG gun for use in high-amperage GMAW applications requiring 400-amp capacity and up to 1/16 inch wire diameter capability. No specific machine or feeder compatibility data was provided in the product input.

Installation Notes

Installation and service should be performed by a qualified welding professional familiar with GMAW equipment. Disconnect power to the welding system and depressurize the shielding gas supply before making any cable or consumable connections. Follow the equipment manufacturer's guidelines for torch-to-feeder mating and ensure all electrical connections are fully seated and secure before energizing. Refer to applicable AWS and facility safety standards during installation.
